It's a favorite assignment in upper-division major courses—have students collaborate on a research project. The rationale is straightforward. Students learn how to do research by doing it. Of course it depends, but in most fields, students new to research find it a daunting process that includes multiple steps: generating a research question, reviewing the literature, designing the study, collecting the data, analyzing them, writing up the results, and then presenting them. Teachers have students tackle the project in groups to make it less overwhelming and to underscore the value of collaboration on big projects.
